rogge1711, Many thanks for your prompt suggestion. Unfortunately, unlike TY2017 (when your solution worked) it did not work for current year. TT TY2018 did not ask me to fill f1116 and appropriately shows the Tax credit on line 48 on the 1040, however, the error listed above continues to occur during "Smart Check". I guess, it is too early and I will have to wait for others to encounter same problem before a fix is offered. Could this be related to the fact that the final form 8960 (Net Investment Income) is will not be available until Jan 31?
